IRFZ46NPBF from Infineon Technologies, in a TO-220AB. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate; controls the channel with VGS rated ±20 V and a threshold of 2.0 V to 4.0 V at VDS = VGS, ID = 250 µA. |
| 2 | D | passive | Drain (also the tab); VDSS 55 V, continuous drain current 53 A at TC = 25°C (package limit 39 A). |
| 3 | S | passive | Source; body diode conducts continuous 53 A and pulsed 180 A to the drain with VSD max 1.3 V. |
